The 24th Amendment to the United States Constitution was ratified on January 23, 1964. It prohibits the imposition of poll taxes in federal elections. Poll taxes were implemented in many Southern states as a way to disenfranchise African American voters. By requiring citizens to pay a fee in order to vote, poll taxes effectively prevented many Black Americans and other minorities from exercising their right to vote.

The elimination of the poll tax through the 24th Amendment was a significant victory for the civil rights movement and played a crucial role in advancing voting rights for African Americans. It helped to remove a barrier that had long been used to suppress the political power and participation of Black voters. The amendment was a key component of the broader efforts to ensure equal voting rights for all Americans, regardless of race or economic status.
